Upgrading to Ubuntu 13.04

Ubuntu 13.04
It's that time of the year! Well, the first one... A new Ubuntu version comes out every April and October.


Ubuntu 13.04, Raring Ringtail, has been released.


Time to do a direct upgrade from my 12.10 installation.


The upgrade process was quite simple. I upgraded some packages normally using Update Manager, and when everything was up to date:



After rebooting, the only thing I had to do was going to "Software & Updates" and in the "Other Software" tab re-add my 3rd party PPAs.

Unity seems faster and everything is running smooth.

Google Play Music

Google Play Music



Google Play Music is finally available in Portugal!

I will show how to set up upload your music in Ubuntu using the Google Music Manager.






Installing Google Play Music Manager in Ubuntu
$ wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | sudo apt-key add -
$ sudo sh -c 'echo "deb http://dl.google.com/linux/musicmanager/deb/ stable main" >> /etc/apt/sources.list.d/google.list'
$ sudo apt-get update
$ sudo apt-get install google-musicmanager-beta
I had trouble with the version installed via ppa, it was always crashing after opening up. I found a working version here.

To download and install this version:
$ wget -O google-musicmanager-beta_1.0.55.7425-r0_amd64.deb http://ubuntuone.com/63gYDtAAJow4nWizbZqM6U
$ sudo dkpg -i google-musicmanager-beta_1.0.55.7425-r0_amd64.deb

Moving your /home partition to a new disk

A couple of weeks ago my hard drive started to fail. The boot time started degrading and a scan to the /home partition would run in every boot. Also sometimes it would return i/o errors.

A look at the disk's SMART data confirmed a number of bad sectors.

So I bought a new disk and migrated my /home partition.


The setup

I have a SSD drive with my root (/) partition and a HDD drive with my /home partition.
I bought a new HDD drive to replace the old one and connected both at the same time for the migration process.


Startup Disk Creator
Booting into a live environment

I installed Ubuntu into a pen drive using the Startup Disk Creator. This allowed me to boot into a full Ubuntu environment without booting from my actual system.


Discover the UUIDs of the drives

Before starting the process we need to identify the drives by UUID.
$ sudo blkid
